Chapter 425: Want to smell it?

  The story of the passenger pigeon, of course, has a lot to say.

   Originally the Indians used smoke to hunt. After the colonists learned it, they felt that it was not efficient enough. They upgraded this method and burned directly with sulfur.

  Passenger pigeons like to huddle together to deal with threats. There may be tens of millions of passenger pigeons inhabiting in a forest, and hundreds of thousands of them can be dropped by sulfur fumigation.

In an Audubon record, hunters rounded up a 300-square-kilometer passenger pigeon habitat. The poisoned passenger pigeons landed like snowflakes, and even crushed the carriage used to carry the passenger pigeon corpses.

  Two farmers simply drove their pigs from more than 100 kilometers away to feed the pigs.

  There are also hunters who, based on the habits of the passenger pigeon, came up with a way to sew the eyes of a passenger pigeon, tie it to a branch with a rope, and set up a net around it.

After hearing the news, the companions of the passenger pigeon came and thought that there was food nearby, so they fell into the trap, and they could catch thousands of them. Such passenger pigeons used as bait are called "match pigeons".

  However, on the outdoor display boards, tourists may not bother to read too much content.

  So just briefly introduced the process of extinction of passenger pigeons.

The story of the extinction of the passenger pigeon has a huge impact, and Liu Wei has also heard of it!

   But I just know a general idea, it seems that there are a lot of them, because of human hunting and extinction.

  I learned these details for the first time, and his eyes widened in shock: "5 billion? Extinct in a century and a half?"

The two pictures of the    exhibition board, the passenger pigeon in the sky like a dark cloud, and the lone passenger pigeon with only one left, also caused a great impact on him.

  What is the concept of 5 billion? Humans seem to be only more than 7 billion.

  It's a bit scary to think about it like this, and I usually live without worries. Since I was a child, I have known that the ozone layer is hollow, global warming, and the environment is deteriorating. I can often do it on reading questions. Writing is also a classic material.

  I only know that I keep mentioning it every year, and it gets worse every year, and I have never felt anything. I always feel that it is far away from myself.

  If there is any huge crisis, such as deadly infectious diseases, nuclear waste water, and nuclear war, how long can human beings live?

Will   , like the passenger pigeon, disappear quickly at some point in the future?

  No way, no way, so scary! I felt a little panicked when I thought about it.

  In front of the passenger pigeon display, some people were silent and sighed slightly, some frowned and thought attentively. Someone just glanced at them and left, and some children laughed and stroked the lower passenger pigeon statue.

  The monitor clapped his hands: "Let's go, let's not look at the pigeons. Let's go to see the giant panda. I checked the guide before and said that the panda is the most active at eight or nine o'clock in the morning! If you go later, you may have a rest."

   "Oh!" everyone cheered and agreed.

  ...

   Come to the Giant Panda Pavilion!

  Although Liu Wei was watching the news before, he saw the appearance of the Giant Panda Pavilion.

  But when I came over at this moment, I couldn't help but be a little surprised: "Wow, this pavilion is so beautiful!"

  "It's really beautiful! Compared with this side, the zoo environment at my home is really the same as the pigsty. I thought the zoo is like that!" Some students were stunned, and the worldview was subverted.

  In spring, vegetation grows and everything recovers!

  The temperature gradually warmed up, and the hot and humid air from the ocean became active. There was a light rain in the first two days.

  The sunshine in the past few months was calm and cold, but now it is warmer and brighter, with a layer of soft gold.

  The blue sky seems to have become clearer.

  After the rain, the vegetation in the pavilion drew out fresh shoots with the rising of the yang, and their vitality began to germinate.

  In such a comfortable weather, Zhuangzhuang also seems very comfortable!

   Lying on his side on the tender green lawn, with one of his own claws on his face, and two black hind legs overlapped, his posture is quite enchanting, like a drunken imperial concubine!

  Looking at a stone in the distance, I don't know what it is thinking about!

  Or just simply in a daze.

  Yang Yue is like a child, smiling sweetly and happily, her eyes are full of excitement, and there is something unbelievable!

   Turned his head and looked at Jiang Lan's expression, exchanged his eyes, as if to say: "It's a panda!"

   Then let out a series of "hehehehe" chuckles!

  Everyone admired the panda with relish, and some took pictures with their mobile phones!

  Zhuangzhuang was in a daze for a moment, raised one arm, stretched out to the sky, his leg moved, his right leg was half-bend, and he rubbed his belly with his heel with a grin.

Rubbing, the body gradually changed from lying on the side to lying on the back, with his right foot scratching his belly and the base of his legs, the raised arm swayed with the tickling, and the left foot did not know when it was up. .

  Looking like this, it should be very comfortable to scratch!

  Everyone couldn't help laughing: "Haha, it's so cute."

   "This shake is so rhythmic!"

  "Swing and swing, let's swing together!"

  After scratching the itching, Zhuang Zhuang's limbs fell back to the ground, turned over and got up.

   Slowly twisting his butt, stepping inside the Bazi, and starting to patrol the exhibition hall.

  Walking to a place close to the glass curtain wall, everyone immediately waved to Zhuangzhuang excitedly!

   "Wow, the panda is here!"

  Wu Jiancong put his palms on the glass: "Panda panda, come and give us a high-five!"

  Seeing a big bear with a wide body and fat, black-and-white color, shoveling away small bushes, stepping from the hillside with thick black bear paws, walking towards him calmly, it is still very visual impact!

  Zhuangzhuang actually didn't even see them at all.

  Initially, the eyesight is not good. The light in the corridor is still darker than the exhibition area, which is a natural light barrier.

  Unless you are one or two meters away from the glass curtain wall, you can see the inside.

  Gradually walked away again and came to a tall and strong tree.

  I found a sack, so he leaned forward and sniffed with interest.

  The sack is suspended from a thick tree trunk with springs and ropes, and contains some bamboo leaves.

  Zhuangzhuang is coming!

  The man stood up, hugged the sack, and his mouth firmly bit the sack.

  One after another, he lay down on the grass on his back!

   Holding the sack and shaking it left and right.

  Because the sack is tied with a spring The toughness of the sack is very good!

   was pulled to the ground, pulled by the spring, and felt like jumping up.

  Zhuangzhuang is holding the sacks tightly, as if fighting and wrestling with a strong opponent, practicing boxing!

Hey! what!

   Shaking to and fro, sharp teeth biting the sack, and soon the sack was bitten and riddled with holes.

  However, Zhuang Zhuang is not very hungry, and is more playing.

  I felt a little tired after playing twice. I didn't want to work so hard. I loosened my sacks and wriggled my hips and walked slowly away.

  Liu Wei saw the guide in work clothes in front of him, surrounded by tourists, who seemed to be explaining something, so he leaned in too.

  I saw the instructor wearing a glove with a green round bar in his hand, and smiled: "Who else wants to smell it?"

   Liu Wei couldn't help but had a bad idea, raised his hand and asked: "Uh...what is this?"

  The commentator smiled kindly: "Panda dung, are students interested in smelling it?"
